je, me, te, se, le, and la become j', m', t', s', l', and l', respectively, before a vowel or mute h. See Elision (French).
In formal French, the pronoun on is often replaced by l'on after a vowel (in particular after et, ou, qui, que, quoi and si); in particular, formal French often replaces si on and qu'on with si l'on and que l'on, respectively. This does not affect the meaning, only the pronunciation. In modern French, on has replaced nous as pronoun for the plural first person. Nous is used in formal usage.
